Nailbender we all do it a little different. I don't think it matters all that much.
Here is what we do: we put the shiners in a bowl try to let the water drip off them in a net before we put them in bowl. Next we pour wintergreen rubbing alcohol over them, just enough to cover them. We let them set for 20 minutes, then scoop them out in net and let them drip again. Then we put them in a ziplock and freeze. We have good luck with them storing all season and they stay firm.

Not as good as live, but the next best thing.
